Jeff/ Steve,

The internal flange does stop some/ perhaps most sound waves from going directly out of the inner tube.

That is correct. There is no packing. The unit is essentially two expansion chambers connected by the center tube.

Steve, I don’t see anything in your muffler that muffles … it looks like an expansion chamber?
